| 1. A network management method for managing an interconnecting network which has a plurality of switch apparatuses each including
physical port units, the switch apparatuses interconnecting computers through physical lines connected to the physical port
units to construct a parallel computer system, comprising:
a logical line constructing step bundling groups of the physical lines into logical lines, respectively;
a data transmission speed acquiring step of acquiring a data transmission speed between computers interconnected through the
physical lines; and
a port control step enabling or disabling the physical lines bundled into a respective logical line by powering ON or powering
OFF the physical port units to which the physical lines bundled into said respective logical line are connected, to dynamically
change to a line transmission speed of said respective logical line in correspondence with the acquired data transmission
speed
wherein the Port control step produces a predicted time schedule of data transmission speed of said respective logical line
from a communication history acquired from the switch apparatuses and, based on the predicted time schedule, powers ON or
powers OFF the physical port units to which the physical lines bundled into said respective logical line are connected.
